IMPROVEMENT IN SHACKLES.

Specification forming part of LettersPatent No. 187,362, dated February13,1877; application tiled March 25, 1875.

To all whom t may concern Be it known that I, HENRY WILLIAM DI'LG, ofPortland, in 'the county of Multnomah, in the State of Oregon, haveinvented an Improved Shackle for prisoners and convicts, of which thefollowing is a specification:

The invention consists in constructing the shackles of two parts orcurved bars, having a loose-jointed or detachable hinge connec tion, andone of them made oi' angular form at the other end, whereby it isadapted to be locked to the other part or bar, as hereinafter described.

In the accompanying drawing, Figures l and 3 are, respectively, aperspective and plan view of the shackle, partly open. Fig. 2 is acrosssection. Fig. 4 represents an ankle-support for the shackle,attached to a shoe.

The shackle is composed of the two parts or curved barsAa-nd B, whichare hinged together at one end and locked together at the other. Thepart or bar A has a curved socket'in its hinge-end, and the part or barB a curved or hook-shaped tongue C, adapted to fit somewhat loosely insaid socket. The other end of the part A is constructed in the form of arightangle, with a rabbet, K, on its inner face, and a holt-hole orsocket in its outer arm, L. rlhe end M ofpart B is provided with aspring locking-bolt L', and a corresponding lip or iange to adapt it tofit and lock together with the right-angular rabbeted portion of thepart A.

It will be perceived that this construction adapts the parts A B of theshackle to be detached or separated one from the other. When it isdesired to apply the shackle to the leg of a prisoner or convict, thetongue C of part B is first inserted in the hinge-socket of part A, andthe opposite ends L M are brought together and locked by the springibolt L. The tongue O then answers as a claw or hook, and thehinge-connection is even more secure than if the parts werepermanently'attached to each other. The ange on part B which enters therabbet K of part A, prevents the insertion of a lever or otherinstrument between them for forcing them apart. rlhe face, or inner sideof the lock, is protected by a plate M', which is inserted in dovetailor under-cut grooves.

Fig. 4 illustrates a form of ankle-support for the shackle, the sameconsisting of a horizontal two-part ring, H I, for encircling the leg ofthe prisoner and a vertical U-shaped bar K attached to the shank of theshoe-sole, said parts H I and K being suitably connected by screws orrivets. The rear part 1 of the ring may be turned on pivot J by firstremov ing the screw J which secures its opposite end to part H.

What I claim is- The shackle composed of the parts A B, the one having ahinge-socket and angular portion, and the other provided with a curvedtongue and a locking-bolt, .as shown and described.
